Starting

✿ Do not simply discard the packing materials

with the house-hold waste. Take the packing

materials to the appropriate collection areas for

recycling.

Dirt in the feed water could lead to the appliance

being damaged. To avoid this risk, we recom-

mend fitting a filter with 3/4" connection (4.730-

059) .

If you are using an extension cable, it should

always be completely unwound from the cable

drum and have a sufficient cross-sectional area

(10 m = 1,5 mm², 30m = 2,5 mm²).

Operation with high pressure

The appliance is equipped with a pressure-ope-

rated switch. The motor starts only if the lever of

the gun is pulled. The pilot lamp is lit as long as

the appliance remains switched on.

The safety ratchet does not lock the lever of the

gun during operation but only prevents it from

opening unintentionally.

Operation with Detergent

✿ We recommend that you use detergent

sparingly for the sake of the environment.

Observe the recommended dosage on the

detergent label.

By offering you an individualised range of clea-

ning and preserving agents, Kärcher guaran-

tees trouble-free operation of the unit. Request

more information or ask for our catalogue and/or

individual information brochures on specific de-

tergents.

• Profi RM 555 ASF, Universal cleaner

This cleaning agent may be used undiluted.

• Profi RM 555 ULTRA, Universal cleaner

• Profi RM 555 ULTRA, Automotive cleaner

• Profi RM 565 ULTRA, House and garden cleaner

• Profi RM 575 ULTRA, Boat cleaner

Before using, these cleaning agents must be

diluted with 9 parts of water (1:9).

We recommend the following cleaning methods:

Step 1: Loosening dirt

Spray on detergent sparingly and allow to react

for a short time.

Step 2: Removing dirt

Spray off the loosened dirt with the high-

pressure spray.

Switching Off

After using a detergent, the appliance should be

rinsed clear. To do this, set the cleaning agent

metering valve to „0“ and flush the unit for ap-

proximately 1 minute with the gun open.

Pull the trigger until there is no more pressure in

the appliance, and secure the trigger with the

safety ratchet against unintentional opening.

Frost will destroy an appliance which has not

been completely emptied of water. Ideally, the

appliance should be stored in a frost-free room.

Troubleshooting

! Note: Disconnect the appliance from the po-

wer mains before all repair work.

Appliance does not Work

- Check whether the voltage shown on the rating

plate corresponds to that of the power source.

-Check the connector cable for damage.

Appliance does not reach Operational Pressure

-Vent the appliance:Allow the pump to operate

without the high-pressure hose until water

appears at the high-pressure outlet without any

more bubbles.Then reattach the high-pressure

hose.

-Clean the strainer in the water connection.

-Check the inlet water flow rate.

-Check all inlet pipes to the pump for leaks or

block-age.

Strong Pressure Fluctuations

-Clean the high-pressure nozzle. Remove dirt

from the nozzle hole with a needle and then

rinse out with water from the front.

Pump Leaks

-10 drops per minute are permissible. In the

case of more serious leakage, you should con-

tact the authorized customer service.

No Detergent Suction

-Set the spray lance to the minimum working

pressure.

-Clean the filter in the detergent tank.

-Clean the ventilation hole in the cover of the

detergent tank.

Spare Parts

A selection of the most common spare parts

numbers is listed at the end of these operating

instructions.

Guarantee

The terms and conditions of guarantee issued

by a national Kärcher Company are valid in the

relevant country.

If the appliance malfunctions in any way, the fault

will be rectified free of charge within the period

of the guarantee provided the malfunction is due

to faulty material or a manufacturing error and

all the terms and conditions are met.

General Information

Purpose

Use the appliance to clean machines, vehicles,

buildings, tools etc.

Clean facades, terrasses, garden equipment

etc. without detergent only with the high-

pressure spray.

✿ Cleaning with the use of a high-pressure cle-

aner brings an 85% reduction in the consump-

tion of fresh water.

✿ Cleaning tasks which produce waste water

mixed with oil – e.g. when washing engines or

the undersides of vehicles – should only be car-

ried out at a specific washing point that is equip-

ped with an oil separator.

Safety Equipment

When the spray gun is closed, the overflow val-

ve switches off the appliance via a pressure-

operated switch. The overflow valve is also a

safety device against exceeding the maximum

allowable working pressure.
